Abstract: The tungsten-halogen lamp holder (3) of the lighting fixture is retained by a mount consisting of two U-profiled parts (6, 7) at a distance behind the reflector shell (1) that can be chosen by displacing the second U-profiled part (7). The reflector shell (1) has an opening (2) through which the tungsten-halogen lamp (4) projects into the reflector chamber (20). The cross-section of the opening (2) is a multiple of the cross-section of the tungsten-halogen lamp, so that a wide annular gap (21) for through-ventilation is free between the tungsten-halogen lamp (4) and the opening rim (9) of the reflector shell (1). In order to form a through-ventilation chamber (22), the mount (6, 7) is completely open to the rear and, moreover, on two opposite sides. The tungsten-halogen lamp holder (3) is freely retained by the mount (6, 7) in the through-ventilation chamber (22) adjoining the annular gap (21), so that the holder (3) is enveloped by the air current flowing through the annular gap (21), and the cap (base) of the tungsten-halogen lamp is cooled. The service life of the tungsten-halogen lighting fixture is thereby substantially increased.

Title: An internal combustion engine camshaft drive mechanism.
Inventor: PARKER PETER HARRY
IPC: F01L1/344
Filed: 1990-10-04
Abstract: A camshaft drive mechanism operates the inlet valves of a first cylinder through a variable valve timing (VVT) mechanism at one end of an engine block and the inlet valves of a second cylinder through a VVT mechanism at the other end of the block. In a four cylinder engine the first cylinder is No 1 and the second cylinder is No 4, cylinders Nos 2 and 3 having separate VVT mechanisms adjacent the VVT mechanisms of cylinders Nos 1 and 4 respectively. A preferred form of VVT mechanism includes an eccentric sleeve which provides a journal for a driving member. Rotation of the eccentric sleeve in an offset bore alters the valve timing. By having the offset equal to the eccentricity of the sleeve the potential wear of the components of the VVT mechanism is reduced.

Title: Appareil et methode de transposition et de compression/decompression de donnees d'images
Inventor: KLEIN ROBERT
IPC: G06T3/60
Filed: 1990-10-04
Abstract: Un circuit intégré spécifique à des applications (CISA) permet la transposition, la compression, et la décompression de données vidéo d'images acquises. Le procédé de transposition associé à ce CISA permet la remise en ordre de colonnes de données d'images à pixels acquises en rangées horizontales, et permet la suppression de données de pixels à analyse dépassante et à analyse dépassante négative, associées à chacune des colonnes analysées verticalement de données acquises. Ces données transposées sont ensuite comprimées à l'aide de technique de codage de Huffman, conjointement avec le codage de longueurs de passages. L'appareil et le procédé de compression/décompression de l'invention utilise une technique de remise en ordre, selon laquelle toutes les prédictions de "fiabilité élevée" sont plaçées dans une extrémité du tampon, et toutes les prédictions de "fiabilité faible" sont plaçées dans une autre extrémité du même tampon. Cette remise en ordre, ainsi que la configuration de fenêtres biaisées et la définition du compte de longueurs de passages associée, permet une compression et une décompression sans perte hautement efficace de données d'images associées.
